Specification of Letters Patent.

I MOP-WRINGEB.

Patented Oct. 1, 1907,

To all whom it may concern:

Be it known that I, ARTHUR M. BURNHAM, a citizen of the United States, and a resident of Gardiner, in the county of Kennebec and State of Maine, have invented ed to me August 11, 1903, No. 736,065, and has for its.

object the improvement of the operating parts of the wringer shown in said patent as will be clearly explained hereinafter and specifically claimed in the appended claims. 4

It further has for its object to provide an improved spring-treadle, spring mop-guide, swinging frame for the movable roller, and means for supporting the movable roller.

It still further-has for its object to provide a mopwringer which is exceedingly simple, inexpensive, and durable in construction, and which can be quickly and easily operated with very little labor.

The invention consists in the construction, arrangement and combination of the several parts, as hereinafter described and claimed.

Referring to the drawings, Figure 1 is a side view in elevation of my invention applied to a pail or receptacle; Fig. 2, a top plan view of same; Fig. 3, a detail view, on an enlarged scale, of a portion of the swinging frame for supporting and carrying the movable rollerfFig. 4, a front view of the mop-guides; Figs. 5 and 6, front and sectional views, respectively, of one of the sleeve-bean ings; Fig. 7, a front view of one of the treadle links; Fig. 8, a fragmental detailview of the stationary roller and its mounting; and Fig. 9, a detail view of one of the springs for operating the treadle.

In the drawings, in which like numerals of reference denote like parts throughout the several views, 1 represents a rectangular pail or receptacle, having revolubly supported at its upper edge, at one end, a stationary roller 2, between which and the movable roller 3 the mop is designed to be wrung.

The stationary roller 2 is journaled on a metal bar 2, having its ends mounted in holes in plates 2, secured to the sides of the pail. 2 indicate collars mourfted on the bar 2 between the plates 2 and the ends of the roller to space the roller therefrom, so as to prevent chafing the ends of the roller against the plates and also to prevent the strands of the mop becoming wedged between the roller and the pail, as well as for the purpose hereinafter stated.

To the ends of the stationary roller 2 are affixed plates 2 2 each of said plates being provided with a hole to permit the passage of the metal bar 2*, said plates reinforcing the material out of which the stationary roller 2 is constructed and forming bearings to support said stationary roller upon the metal bar 2 when said stationary roller 2 is being revolved during the process of wringing the mop. A

Metal reinforcing strips 2 2 are secured to the sides of the pail 1 in any suitable manner, each of the said strips having a hole therein to permit the passage therethrough of metal bar 2", and between said reinforcing strips 2 2' and the plates 2 2 metal collars 2 2 encircle the bar 2, the said reinforcing strips and collars fixing the ends of the roller 2 at a sufficient distance from the sides of the pail 1 to permit the unimpeded movement of the said roller while it is being revolved, and also to permit the handle of said pail to be dropped and to lie alongside of each end of said roller 2, and between the said ends and the sides of the pail or receptacle 1.

To the sides of the pail 1 bars 4 are secured and are bent into the compound curve shown and project beyond the forward end of the pail, forming feet 4, to

prevent the upsetting of the pail or receptacle when applying pressure on the treadle in the process of wringing the mop.

To the bars 4 a swinging frame 5 is pivotally connected by means of screws or bolts 6, or in any other suitable manner, and said frame comprises a bar of metal, preferably round in cross-section, bent at six points between its ends, as at 5", 5 5, 5, 5 5, pro-. viding a straight portion 7, which extends through the longitudinal center of the movable roller 3, the ends of the said swinging frame being pivoted to the bars 4, in any suitable manner. I

A metal plate 3 is secured to the ends of the movable roller 3, each of saidplates being provided with a hole through which the straight portion 7 of the swinging frame 5 'is projected, said plates reinforcing the material out of which the movable roller 3 is constructed and forming bearings to support the movable roller 3 on the straight portion 7 of the swinging frame 5 when said movable roller 3 is being revolved during the process of wringing the mop.

The swinging frame 5 is held in its normal position against the top of the pail or receptacle 1, at one end,

by a spring 8, which comprises a spring wire coiled between its ends and having one end bent around and secured to a rivet 9 on bar 4, and then bent at right angles, forming a lug 10, projecting under the lower edge of bar 4, to prevent the pivotal movement of rivet 9. The other end of the spring extends upward and is formed with a hooked end 11 removably and replaceably secured to the swinging frame 5.

The bars 4 have secured thereto by means of bolts 12 or in any other suitable manner sleeve-bearings 13, to pivotally support my improved treadle 13, which comprises preferably a piece of heavy spring-wire bent at two points between the ends, forming the treadle or foot portion 14, and the middle portions of the treadle are coiled, as shown at 15, and are supported on the sleeve-bearings 13. 13 13 indicate an arm rigidly secured to the free ends of the side arms 13 of the treadle. and are provided with holes to receive the sides of the swinging frame 5 near the pivotal points thereof when the wringing is not in operation but which slide on the sides of the frame 5 away from the pivots 6 when the foot portion 14 is depressed to swing the roller 3 towards roller 2, as hereinafter described.

17 17 are two metal strips riveted or otherwise suit ably secured to opposite sides of the pail or receptacle 1, said strips being bent obliquely inward. as at 17 17 and then again bent, as at 17 17 on a line substantially parallel to the direction of the first portion of the strips the free ends of said strips 17 17 extending to near the bottom of the roller 2, forming a guide to direct the mop to the central portion of roller 2 and in position to be most effectually squeezed between the rollers 2 and 3. The free ends of the metal strips 17 17 are so bent, at 17 b 17 that the upper edges thereof are slightly farther from the sides of the pail or receptacle than the lower edges oi the same.

The operation of my invention is as follows: When a mop is to be wrung it is placed in the pail or receptacle 1 and directed by the guide 17 17 to the central portion of roller 2. The operator then presses down on the front portion 14 of the treadle 13 to swing roller 3 over against the mop and press it between the rollers to effectually wring the Water from the mop when it is drawn from between the rollers. l3 on the ends of the treadle 13 engage swinging frame As the arms 13 l 5 near the pivotal support of the frame, said arms 13 13 will moye frame 5 a considerable distance with comparatively slight movement of the treadle lil. and as the frame moves toward the roller 2 the arms iii" 3 will move away from the pivots (i, and a greater leverage is exerted by the treadle to effectually squeeze the mop.

13y constructing the treadle 13 of heavy spring wire and the guide 17 1.7 of spring metal. and shaping and mounting the guide l7 17 as above explained, they will yield to compensate for tangles or bunches of the mop and not injure the wringer.

Having thus described my invention. what. l claim as new is In a mop-wringer, the combination of receptacle. a roller journaled on said receptacle, curved bars secured to the outside of the receptacle and having projecting ends forming; feet to brace the receptacle, guide strips secured on the inside of the receptacle and having the portions under the roller aforesaid closer together than the remainder thereof, a substantially Ushuped frame pivotally secured at its free ends to the curved bars at'oresa id. the

,middle portion of said l'rnme bent back on itseltf and provided with a straight portion, a roller journaled on said straight, portion, :1 spring secured to one of said curred bars and remorahly secured to one of the side bars of said pivoted frame. a substantially U-shaped treadle. the sides of said t'readle bent to form loops, sleeves iournaled on said curved bars and inserted in said loops, and arms so cured to the free ends of said Ushapcd t'readle and provided with holes to receive the side bars of the Ushaped frame, substantially as shown and described.

In witness whereof, I have hereunto set; my hand in presence of two subscribing witnesses.
